Method and means for producing textile materials comprising tape in two oblique orientations

摘要

A novel method and means for directly producing a variety of textile materials comprising tapes oriented in two opposite oblique orientations relative to the textile's length and width directions, called Oblique Fiber Textile (OFT), are disclosed. The described method and means for producing OFT provide secondary structural integrity/stability to OFTs, in addition to primary structural integrity/stability. The process is especially advantageous for producing OFTs comprising tapes, including Spread Fiber and Highly Drawn Polymeric types. Such OFTs are needed in a number of applications such as ballistic mitigation, composite materials, safety products etc. for their improved performance, functions and aesthetics. Several different types of OFTs are producible by the novel OFT forming process which is technically unlike weaving and braiding processes.

主权项

1. A method for producing a fabric material comprising tapes, wherein all the tapes are arranged in oblique orientations in relation to a fabric length direction, said method comprising:
laying tapes, successively, in at least two mutually angular directions, each of said angular directions being oblique in relation to fabric length and width direction, the laying of tapes comprising drawing out tapes from at least one tape supply source and placing the tape in a relation to previously laid tapes on a working bed; displacing, fore ends of some of the previously laid tapes in a thickness direction of the tapes, for laying of tapes between said displaced tapes and non-displaced tapes; consolidating the produced material; advancing the produced material; and taking-up the produced material in fabric length direction.
